Ok, just have a couple of questions that maybe someone can answer for me:

A little background first, I have some PC parts laying around and decided I wanted to make an LCD side panel for poops n giggles. I have all the parts (I think) I need already but before I get started I wanted to ask for some info.

1. I need 12v/4a to connect to the LCD mainboard, is there a PSU connection (4pin/12pin etc) that will output that without a stepdown/up? Eg: Take off the cable connector, slap on a 12v Barrel head adapter and off I go.

2. Is there a standardize Volt/Amp output for PSU's Connectors or is it all based off PSU Size (Wattage)?

This one I don't know and I am not going to be able to answer

There is ground and +12v on many connectors.. If that helps.

All of the connectors on a power supply have at least one 12v wire.

If the cables are colour coded then 12v is yellow. Otherwise check the pinout for the connector or better yet use a multimeter.

Voltage is standard. PSUs output 12v, 5v, 3.3v. some PSUs are 12v only. You can view the output voltages on the label of the PSU.

The voltage should remain constant. It's the current which changes depending on the load of whatever is drawing power.
